Design review: the 10s blind-reset watchdog decided correctness from a wall-clock threshold. Rework piece 1 into a deterministic two-part design (pieces 2 and 3 — lifecycle-reset counter zeroing and powerMonitor wake IPC — are unchanged): - Cumulative ACKs (TCP-style): the renderer dispatcher now tracks a monotonic per-pty total of processed chars (terminal-pty-ack-gate) and sends it on every ACK alongside the legacy per-chunk delta. Main keeps per-pty sentChars/ackedChars and max-merges received totals — idempotent and reorder-tolerant, so a lost ACK self-heals when any later ACK arrives instead of becoming permanent in-flight debt. Provider (SSH/daemon) backpressure is credited only the derived delta, clamped, never negative. Main tolerates both payload shapes keyed by field presence (dev hot-reload can mix renderer/main versions); totals reset on pty exit and renderer lifecycle reset on both sides. - Solicited resync (replaces the blind reset): when new pty data arrives while that pty's delivery is fully gated and no probe is outstanding, main sends pty:requestDeliveryResync; the renderer replies with its cumulative totals and main reconciles via max-merge, then flushes held pendingData. Event-triggered, verified-state recovery — no wall-clock threshold decides correctness. The only timer is a 5s request/response hygiene timeout that clears the outstanding flag and logs one diagnostic warn per silent streak; it never mutates counters (a renderer that cannot answer has dead IPC — reload is the only cure). The 10s corrective watchdog is deleted. Co-authored-by: Orca <help@stably.ai>
